I'm wanting to use my Virgin Mobile SIM which I guess will lock onto EE/Orange/Tmobile. I hear they are a real pain to get unlocks from? Does me being a VM customer for 6months+ entitle me to the unlock as well or I have to go direct?
If not, is it better I just try get an o2 SIM and use their direct service or http://www.cellunlocker.net ? (They are charging $40 with 5-15 day average time)
I'm afraid there's one problem here, Virgin don't support the iPhone, therefore won't unlock any iPhone locked to their network. There may be exceptions to this, but I've had a number of people tell me they can't get an iPhone unlocked because Virgin refused to do it.
